Frequently Asked Questions

What is happening?
A new 2.1 kilometer sanitary sewer is being built to provide wastewater servicing to the Yonge Street and Highway 7 area to accommodate anticipated population growth.

As part of this project, intersection improvements at Highway 7 and Silver Linden Drive and Highway 7 and Bayview Avenue will be made to meet the requirements of the Accessibility for Ontarians with Disabilities Act.

What is the construction timeline?
Construction of the sanitary sewer and intersection improvements will begin in the summer 2021 and be completed in 2023.

How will the sewer be built?
Most of the sanitary sewer work will be constructed using a trenchless technology referred to as microtunnelling.

What is microtunnelling?
A machine will create tunnels underground and install the sewer pipe approximately 8 to 10 meters below the surface. The use of the microtunnelling construction method will minimize the impacts to local traffic.

What are the intersection improvements?
The work will improve the function and accessibility of the intersection according to the Accessibility for Ontarians with Disabilities Act which includes installing accessible sidewalks, crosswalks and pedestrian signals. During the work at the intersection, temporary signals will be installed.

What are the impacts to traffic?
There will be temporary lane restrictions and periodically limited access throughout the duration of the project. Any work temporarily impacting driveways will be coordinated with the individual property owners before the work begins. Traffic monitoring personnel will be on-site, as needed, to assist with the movement of traffic and reduce any delays.

Will there be sidewalk disruptions?
Sidewalk closures will be avoided as much as possible, however, to safely complete the work, periodically sidewalks will need to be closed. Directional signage will be in place to help guide pedestrians around the closure.
